Bug ID: 93896
Summary: Nvidia GeForce GTX 970M unsupported, no backlight
control
Product: Mesa
Version: 11.0
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: jvoss-Cpl0xJrrQRvQT0dZR+AlfA@public.gmane.org

Video BIOS
The driver cannot load the firmware nvidia/gm204/fecs_inst.bin.
Xorg won't load the nouveau driver because Unknown chipset: NV124.
The backlight does not work.
The following commands have no affect on the brightness:
echo 2 |sudo tee /sys/class/backlight/acpi_video0/brightness
echo 10 |sudo tee /sys/class/backlight/acpi_video0/brightness
Brightness works with the proprietary nvidia driver.
If mmiotrace logs are beneficial, I will add them.

Many thanks, great work on the GL support. Backlight is still not supported as
far as I can tell on kernel 4.6.2 and Mesa 11.2.2.

Try the following patch:
https://lists.freedesktop.org/archives/nouveau/2016-May/025081.html. You should
be able to change the brightness through
`/sys/class/backlight/nv_backlight/brightness` with it.

That fixed it. Thank you very much! Home users will want it to be connected to
xbacklight so that the fn controls will increase and decrease the backlight
intensity, but I am quite happy to run a script.
